DRV8328xEVM User's Guide
This document is provided with the
DRV8328x data sheet (DRV8328 4.5-V to 60-V Three-Phase Smart Gate
implementation of the EVM and shows how to set up and power the board.
The DRV8328AEVM comes automatically populated with and configured for the DRV8328A. It is also
compatible for the DRV8328B, DRV8328C, and DRV8328D variants (see
3.4.2), but the user will need to modify the board to make it compatible for each variant (see
and
Table
3-4).
